Plant irises properly
At the end of July, the time window opens to plant irises in the bed. Plant the tubers in a sunny, sheltered spot in nutrient-rich, well-drained soil well into October. Proceed with these steps:
Compact the soil with your hands and water. If you plant irises in a circular arrangement in the bed, the flower is particularly decorative.

care tips
Planted professionally in the optimal location, the flower requires little care. A well-rooted iris is content with natural rainfall and a minimal amount of nutrients. The details at a glance:
Rejuvenation by division is recommended every 3 to 4 years so that each individual flower retains its vitality for a long time.
Which location is suitable?
The central criterion for the choice of location for all iris species is a sunny, wind-protected location with as many hours of sunshine per day as possible. Exceptions confirm the rule, such as the Siberian meadow iris, which prefers a semi-shady place. This is followed by the requirements for the soil conditions, which are to be determined adequately for the preferred variety. You are correct:
Due to its voluminous bulb, the elegant flower is only suitable for the tub if it is a dwarf iris. In this case, use a high-quality compost-based potting soil as a substrate, enriched with sand or expanded clay.(19.73€)

What is the best planting time?
The best time to plant irises is from July to September. In the sun-warmed soil, the bulbous plant establishes itself in no time at all, so that it has deeply rooted itself in the soil in time for winter.
Continue reading
When is flowering time?
The central flowering period of irises extends from early May to mid/late June. At this time, the bearded iris (I. barbata-elatior) shows the flower power it has, followed by the Japanese magnificent iris (I. kaempferi) in June and July. In the weeks before, in April, the small iris (I. barbata-nana) stretches its blossoms towards the sun.

Properly cut irises
Cut the flower in two stages. First cut the withered flower stalk up to 10 centimeters above the rhizome. The leaves remain on the plant until winter so that the remaining nutrients can be utilized. After the first frost, cut off the foliage close to the ground.
Continue reading
Fertilize irises properly
Fertilize your iris as little as possible. This means that the nutrient supply is limited to an organic initial fertilization with compost, horn shavings or guano in March. If there are signs of deficiency, such as yellowing leaves or a stunted flower, apply another portion of compost. Complete mineral fertilizers are not suitable for the nutrient supply, as the high salt content damages the sensitive tubers.

propagate iris
The iris can easily be propagated by division. Choose a date between the end of July and the beginning of October. How to do it right:
Without further delay, plant the tuber parts at the new location in such a way that half of the rhizome is visible.
Continue reading
How do I plant correctly?
Transplanting the iris every 3-4 years acts as a makeover. A day between the end of July and the beginning of October is best suited for this measure. This is how the process worked:
Now select all the plump, strong tuber pieces to plant them in the new location. The most important criterion is again that a rhizome is still visible after transplanting. Leave the foliage on the iris until the first frost so that the nutrients can still be absorbed.
Continue reading
Is iris poisonous?
When it comes to assessing the poison content, the yellow iris, also known as the marsh iris, becomes the center of interest. This species is more common in the wild along water bodies and is a protected species. That's a good thing, because there are pungent substances in their plant pathways that can trigger nausea and vomiting when consumed. However, since this flower does not taste particularly good, dogs, cats, horses and grazing livestock are particularly affected.

Iris does not bloom
If the iris no longer wants to bloom, the following revitalization treatment gives it fresh strength:
The spent tuber pieces are disposed of in the compost. Plant the fresh parts in such a way that they stand a little above the ground.

The iris in the garden
In the garden, an iris will do its best if you give the flower a sunny, airy location. The soil should be slightly calcareous, humic and well drained. Plant a tuber in a 3 centimeter deep pit between July and October. If the rhizome is still visible afterwards, you have done everything right. How to care for the flower in the garden with expertise:
If the flower in the bed does not want to bloom anymore, dig up the tuber and divide the young segments with at least one fan leaf. Then replant the irises in the new location.
Continue reading
Plant the iris
As a bulbous plant, the iris requires a rethink if you want to plant the flower properly. Plant the rhizome only deep enough so that half or a third of it is still visible. This premise also applies to planting in tubs. Finally, press the substrate firmly with your hands and water.
Continue reading
share iris
Dividing an iris is very easy to do. The weeks from the end of July to the beginning of October are considered the ideal time corridor for this measure. Completely dig up the rhizome of the flower to split with the spade. Then cut the fan leaves in a wedge shape and shorten root strands that are too long.
Plant the tuber segments again so that they are half or at least a third above the surface of the earth. It is important to note that the roots are directed downwards. They offer a divided iris excellent growth conditions when the excavation of the planting hole is enriched with compost or guano.

The flower of the iris
The picturesque beauty of an iris flower comes from a unique combination of petals:

Germinate the seeds of the iris
In order to motivate the seeds of an iris to germinate, the first step is to cut off the seed coat down to the embryo. Then subject the light germs to a 4-5 week cold treatment in the cold house or in the vegetable compartment of the refrigerator. Germination then begins in a semi-shady location at room temperature. Between 3 and 6 years pass before the first flowering.
Sow iris seeds
The seeds of an iris can be sown throughout the year. Hobby gardeners who don't shy away from the challenge can go about their work in these steps:
If you then sow at room temperature, you can look forward to the first seedlings after a few days.

The iris in autumn
In autumn, wait until the leaves of an iris are completely withered. Until then, the tuber will absorb the remaining nutrients in order to create a depot for the next season. Then remove all the leaves with the secateurs. Do not cover the flower with fleece or foliage in the fall. The iris is completely hardy.

Is the iris hardy?
An iris is completely hardy. No special precautions are required to protect against frost and snow. Rather, covering will cause damage to the flower as the rhizome could rot.
